. If you have access to video editing software, record a 320x240 video clip of a “talking head”. Create three version of the video. By any means available to you, create a version that is 75% of the original file size. Create a second version that is 50% of the original file size, and create a third version that is 25% of the original file size. Invite eight different people to view the three versions and to rate each one after they have seen it. Report on your results
